Advanced Features & Functionality of H.265 Megapixel IP Surveillance Cameras


Whether it’s clearer images you require, a better range or more convenience, options exist for you to improve the video surveillance at your business.  Our new lines of high-performance megapixel IP surveillance cameras deliver advanced performance and specialized features as explained below.


Smart Encoding

The Smart Encoding feature optimizes bandwidth and storage space by allowing users to increase or decrease image quality for selected areas based upon criticality. Users can define the stream so security personnel can quickly zero in on the key elements of the scene during preview and playback.


ROI (Region of Interest)

ROI is an image cropping feature designed to assist users in achieving bandwidth and storage optimization. Users can select key regions of a scene to transmit as separate streams for targeted preview and recording.


WDR (Wide Dynamic Range)

WDR technology ensures proper lighting contrast and image clarity when experiencing severe backlighting or glare. True WDR, a sensor-based WDR technology, is perfect for the most challenging lighting environments; WDR can be adjusted to produce the best image under various lighting conditions.


Enable objects in both bright and dark areas to be visible.


Smart IR Technology

IR or night vision cameras that use infrared light to illuminate images in the dark

Some cameras offer Smart IR technology that maintains proper exposure in the scene and includes narrow and wide angle LEDs that manage beam spread that adjusts to the lens field-of-view. The result is greater effectiveness for demanding applications such as identification of people or vehicle license plate numbers under low visible light conditions.


Video Content Analysis (VCA)

Capability of automatically analyzing video to detect and determine temporal and special events

VCA provides a highly reliable and accurate tracking engine with intelligent detection filters that automate the monitoring and analysis of CCTV images. VCA is designed to operate in a wide range of surveillance situations including intrusion detection, vehicle monitoring, abandoned object detection, people counting and loitering detection.


V800 Series Analytic Capabilities


Tampering

Scene change triggers event (blocking scene, changing camera position)


Intrusion Detection

If a person remains in a pre-defined virtual region, the camera will automatically detect the event and can trigger alarms or recording


Intelligent Video Motion Detection

Detects movements of objects
within an environment


V940 Series Analytic Capabilities


Intrusion

Detects intrusion of a set area


Line Cross

Event is triggered when objects cross a virtual line


Tampering

Scene change triggers event (blocking scene, changing camera position)


V940 Series Starlight Features

Starlight cameras utilize a highly sensitive sensor which provides the ability to monitor areas where ambient light levels are extremely low. This technology allows the camera to continue providing video in color when a typical camera has switched to night mode (B&W) further enhancing id/tracking efforts.

Starlight technology is recommended for areas where lighting at night is poor such as public parking lots, recreational areas, playgrounds, banks, restaurants, night clubs and more.

Starlight camera remained in color, day mode, while the regular camera has switched to B/W night mode.

Better clarity of the Starlight cameras in lower light levels, with sensitivity of up to 5x a typical camera, Starlight
cameras are capable of  providing highly detailed information when other cameras cannot.


V940B/D Series WDR (-XW) Capabilities


V942D-XW with WDR disabled

Comparison Between H.265 (HEVC) and H.264 (AVC)

H.265 delivers advanced compression that captures surveillance video using a decreased bitrate, reducing bandwidth requirements and storage costs

Compression Ratio –According to wiki and official test, what differs H.265 from H.264 is the compression efficiency. H.265 (aka HEVC) doubles the coding efficiency compared with its predecessor H.264. This means H.265 video saves around 50% of the bit rate at the same quality of coding.

Bandwidth Use – H.265 is superior to H.264 regarding the bandwidth usage. Because H.265’s algorithm uses the efficient coding, H.265 promises approximately a 40-50% reduction in transmission bandwidth needed to compress the video (e.g., in 720p) over H.264 at the same video quality.

Quality- The big difference between H.265 and H.264 lies in the video quality at the same bit rate. In H.264, the border areas of the block are likely to be distorted, because each macroblock is fixed and the data is independent from each other. H.265 offers sharper details on faces and fabrics and smooth gradient areas with less blocking and fewer artifacts. So H.265 is better than H.264 when it comes to compressing a video with better image quality.

File Size – The improved compression ratio also has a great relationship with the digital storage requirement of video streams and transmission. The reduced bandwidth leads to a smaller file size. Test shows a video encoded with H.264 is almost 1-3 times larger than that with H.265. This is favorable for hard drive storage or the device with limited storage space required to house the video data.


Image Comparison: 1080P and 4MP

What’s the difference?

1080P HD – 1080P provides remarkable clarity. 1080P cameras produce images with 1920 x 1080 pixels per unit. Also known as “full HD,” this is the standard. This image quality is roughly equivalent to 2.1 megapixels.

4MP Ultra HD – 4 megapixel IP cameras are network-based security cameras that are capable of providing video resolutions up to 2560 x 1440 pixels, which is 30% greater than 1080P HD. The 4MP image has twice the detail of the 1080P image, however, by increasing the image resolution, the required network bandwidth and storage will increase accordingly.
